Common Twitter Image Mistakes

Wrong Aspect Ratio

Images that aren't 16:9 get cropped automatically by Twitter, often cutting off important elements or text.

Vertical Images in Feeds

Vertical images don't utilize feed space effectively and create excessive whitespace. Horizontal 16:9 is optimal.

Text Too Small

Text in images must be large enough to read on mobile devices where most Twitter engagement happens.

Ignoring Twitter Card Optimization

Link preview images need special attention to display well in Twitter Cards. Always use 16:9 for best results.

Twitter Card Optimization

What Are Twitter Cards?

When you share links, Twitter creates preview cards:

  • Summary Card: Shows image, title, description
  • Summary Large Image: Featured image display
  • Player Card: For video content

Best Practice: Use 16:9 images for optimal Twitter Card display.

Optimizing for Link Shares

  • Use descriptive, engaging images
  • Include brand elements for recognition
  • Ensure quality even when scaled down
